ALABAMA AGREEMENT STATE REPORT - LOST GENERALLY LICENSED PROCESS GAUGE

The following information was obtained from the State of Alabama via facsimile:

"On May 5, 2016, it was determined that Millennium Resources, LLC, Graysville, Alabama had lost control and possession of a generally licensed device (Ronan SA1-C5 #2255GO containing 5 mCi of Cs-137).

"During a requested visit by the new owner Cane Creek, LLC on April 7, 2016, it was determined that they possessed a new generally licensed device. The new owners only knew that the site once contained a similar plant which contained a device with radioactive material. The old plant was constructed in 1997, and our [Alabama Department of Public Health - Office of Radiation Control] records show that device being received by Millennium Resources, LLC on November 14, 1997. The plant was torn down and sold for scrap during the year of 2006. The new owners had no information in regards to whom the scrap was sold or the whereabouts of the device.

"On April 7, 2016, the Agency [Alabama Department of Public Health - Office of Radiation Control] contacted Ronan and their records indicated no transfer for disposal. During the next few weeks, several calls were made to the Alabama Department of Environmental Management and the Alabama Surface Mining Commission to determine if any new information could be obtained. None of the representatives could provide any additional information.

"As of today [5/6/16], 0915 CDT, the device containing radioactive material has not been recovered. This incident remains open until further investigation can be completed."

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

PART 21 FINAL REPORT- DEVIATIONS ON STRUCTURAL MODULE VOGTLE UNIT 3 AP1000 PROJECT

The following was received via fax and is summarized below:

"The attachment to this letter provides a report in accordance with 10 CFR 21.21 pertaining to deviations and potential defects in structural module CA33 for the Vogtle Unit 3 AP 1000r project. This issue was previously described in interim reports submitted by Greenberry in letters dated June 24, 2016 (NRC Log No. 2016-36-00, Accession No. ML16188A160) and July 26, 2016 (NRC Log No. 2016-36-01, Accession No. ML16229A180).

"During fabrication of other submodules for CA35, it was discovered by Greenberry personnel that some weld cracking had occurred. During metallurgical examination, a second condition was discovered of presence of a heat affected zone and cracks in plate edges induced by plasma cutting in an area not to be welded. In order to evaluate the extent of the condition, Greenberry Industrial requested that the purchaser, WECTEC LLC, return the CA33 submodules that had already been delivered. The returned components have been inspected and it was determined that weld deviations were also present in the previously delivered submodules. Due to the use of the same plasma cutting method on CA33, it is expected that the plate edges on the returned CA33 modules also have cracks on the unwelded edges from the plasma cutting. The plasma cutting induced cracks on subsequently welded edges are typically mitigated by the welding processes for the affected edges. The cracks remaining in unwelded edges may not be a detrimental condition. This will be determined as part of further analysis of the identified conditions.

"The affected material with weld defects has been returned by the purchaser, WECTEC LLC, to the supplier, Greenberry Industrial. Identification and resolution of other affected modules due to plate edge cracking will be performed when the technical evaluation of that condition is complete. The plate edge cracking may not be detrimental to the component performance.
